About this 3.08ct lab-grown oval diamond

This 3.08ct lab-grown oval sits in the three to five carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG849637218 or 849637218. Listed at 12 retailers as of November 5, 2026, with prices from £264 to £1,845, a £1,582 spread on the same certified stone. Brilliant Earth lists it at £1,845. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
